Description

[Detailed description of the invention]

[0001]

[Industrial application fields] The present invention relates to pigeons, crows, sparrows,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing birds such as starlings from entering a veranda or an opening of a veranda or the like in order to prevent birds such as starlings from stopping on a veranda, balcony, handrail, or the like of an apartment or building and being soiled with feces.

[0002]

2. Description of the Related Art Conventionally, there has been known an apparatus which is installed on a veranda, balcony, handrail, or the like of an apartment or building to prevent birds, especially pigeons from invading (for example, Japanese Patent Publication No. Hei 3-6).
No. 9253). In addition, the present applicant has proposed a bird repellent device in which a pair of columns are erected on a handrail, a wire is stretched between the columns, and a magnetic body is provided on the wire (Japanese Utility Model Application No. Hei 4-9389).
No. 7).

[0003]

All of these are effective for preventing the pigeon from stopping on the handrail, but when the veranda is wide, many intrusion prevention devices must be installed. It was not always effective against birds trying to invade directly through the window. Therefore, a method of fixing and attaching a net or the like to the entire opening of a building such as a veranda is conceivable. However, in the event of an emergency such as a fire, the net may obstruct the firefighter's activities. In view of the above, it is an object of the present invention to provide a bird intrusion prevention device that can prevent birds from entering a veranda or the like, and that can be easily removed in an emergency such as a fire and does not interfere with firefighting activities.

[0004]

In order to achieve the above object, a bird invasion prevention device according to the present invention is provided with a drum mounted above an opening of a building or the like, for example, a ceiling surface, and provided in the drum. A plurality of vertically parallel blind-shaped wires wound around a take-up spring, a rod horizontally connected to the free end of the wire, and a latch attached to the rod It consists of:
If the opening is very wide, a motor may be used in addition to or instead of the winding spring. The wires should be of sufficient length to close the opening in the building, depending on the building, preferably about 2-3 meters, and the spacing between the wires is preferably a few centimeters to several centimeters. Further, a magnetic body may be provided on a part or all of the wire. In this case, if it is provided on a part of the wire, it is preferable that every few wires are provided, and if it is provided on all the wires, the mounting height may be changed so that the magnets do not stick to each other. The number of magnets attached to one wire is one to several.

[0005]

The drum of the birds intrusion prevention device constructed as described above is mounted on the ceiling surface of the apartment, such as the veranda opening. When the rod connected to the wire is hooked on the hook provided on the pulling wall, etc. against the take-up spring in the drum, the blind-shaped wire closes the opening. If this is done, birds will not be able to invade and will not be polluted by feces. Also, if a magnetic body is provided on this wire, within the range of the magnetism, the bird's natural biomagnetism will be affected, and it will be surprised as if shocked by feeling the magnetism and will fly away suddenly. For this reason, it does not come close to the veranda itself, and not only feces but also dropped feathers can be eliminated. Since this magnetism affects biomagnetism, it is unfamiliar and has a long-term effect, and a longer duration can be obtained, especially when a permanent magnet is used. When the bedding is dried on the veranda or in an emergency such as a fire, the wire is instantly rewound into the drum by the force of the spring just by releasing the engagement.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the birds intrusion prevention device, and FIG. 2 is an enlarged sectional view of a main part thereof. In these figures, reference numeral 1 denotes a veranda of a condominium or building, a ceiling surface 3 of an opening 2 of a balcony, or the like. A drum 5 suspended by a screw 4 or the like is a large number of parallel wires connected to a take-up spring 6 in the drum 1. In this embodiment, wires having a length of 2 to 3 meters are arranged at intervals of about 3 cm. It is stretched over the blinds. Reference numeral 7 denotes a rod member which is laterally connected to the free end of the wire 5 and 8 denotes a hook attached to an appropriate portion of the rod member 7. 10. Numeral 11 is a spherical magnetic body provided on the wire. The ratio is one centimeter for every two or three wires, and the distance L from the magnet to the rod 7 is about 15 cm.
These will vary depending on the type of bird. FIG. 3 is a perspective view showing a use state when the intrusion prevention device of the present invention is mounted on a veranda. It is the one that several were added. FIG. 4 shows a state of use when attached to the veranda, but unlike FIG. 3, the handrail wall surface of the veranda is an example of the pipe 12. In this case, when the hook 10 is not provided on the pipe 12, it is provided on the base 13 of the handrail.

[0007]

As described above, according to the present invention, when it is desired to prevent birds from entering, only the rod (wire) is hooked on the hook provided on the pulling wall against the winding spring in the drum. The wire is formed in a blind shape. This prevents the birds from entering because the wires hinder the wings.
Also, in the case of drying the futon or in the event of a fire or the like, it is possible to release by simply releasing the engagement, and the wire can be pulled out and rewound with one touch. Furthermore, if a magnetic body is attached to the wire, the bird will be affected by the biomagnetism that the bird is born with and will not dislike the magnetism and will not approach the range where the magnetism can reach, so that the bird can surely be prevented from flying. Since no drug or the like is used at all, it has an effect such as being safe.
